(Main)Low-voltage fuses - Part 7: Supplementary Requirements for fuse-links for the protection of batteries and battery systems
Low-voltage fuses - Part 7: Supplementary Requirements for fuse-links for the protection of batteries and battery systems
These supplementary requirements apply to fuse-links for the protection of batteries and battery systems, including, but not limited to terminology, for electricity storage in equipment for circuits of nominal voltages up to 1 500 V d.c. Their rated voltage may be higher than 1 500 V d.c. The object of these supplementary requirements is to establish the characteristics of Battery fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical.

IEC 60269-7:2021 Ces exigences supplémentaires s'appliquent aux éléments de remplacement utilisés pour la protection des batteries et des systèmes de batterie, y compris, entre autres, la terminologie, pour le stockage de l'électricité dans les équipements pour les circuits de tension nominale allant jusqu'à 1 500 V en courant continu.
Nizkonapetostne varovalke - 7. del: Dodatne zahteve za taljive vložke za zaščito baterij in baterijskih sistemov (IEC 60269-7:2021)
Te dodatne zahteve veljajo za taljive vložke za zaščito baterij in baterijskih sistemov, kar med drugim vključuje tudi terminologijo, v zvezi s shranjevanjem električne energije v opremi za tokokroge z nazivno enosmerno napetostjo do 1500 V.
Njihova nazivna napetost pri enosmernem toku je lahko večja od 1500 V.
Cilj teh dodatnih zahtev je določiti lastnosti baterijskih taljivih vložkov na način, da jih je mogoče zamenjati z drugimi taljivimi vložki, ki imajo enake lastnosti, pod pogojem, da so njihove mere enake.

Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.

Part 7: Supplementary Requirements for fuse-links
for the protection of batteries and battery systems
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

Part 7: Supplementary Requirements for fuse-links
for the protection of batteries and battery systems
1 General
Fuse-links for the protection of battery energy systems shall comply with aIl requirements of
IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the
supplementary requirements laid down below.
1.1 Scope and object
These supplementary requirements apply to fuse-links for the protection of batteries and battery
systems, including, but not limited to terminology, for electricity storage in equipment for circuits
of nominal voltages up to 1 500 V DC.
Their rated voltage can be higher than 1 500 V DC.
The object of these supplementary requirements is to establish the characteristics of battery
fuse-links in such a way that they can be replaced by other fuse-links having the same
characteristics, provided that their dimensions are identical.
